Is repetitive subject left out? Or does "of" mean "by far"?

[eggcracker]

I saw a sentence which quite confusing because of "of".
Is "many of the planes" left out in this below sentence? Or "of" mean "by far"?
"Many of the planes she flew were of dangerously experimental design."

Any explanation would help me a lot. Thank you in advance.

The sentence is fine as it is.

I don't really see how you think that sentence could be constructed with another 'many of the the planes'. The design of the planes was dangerously experimental.

The planes were of a specific design.
Many of the planes were of a specific design.
Many of the planes were of dangerously experimental design.

A dangerously experimental design was used to build many of the planes. Consequently, many of the planes are of that design.

Hello.
I'd like to check if I understand the matter correctly if I may.(I think I can understand eggcrackers confusion.)

I can think of several expressions using 'be of...'

1. be of good quality
2. (be) of noble birth
3. be of importance/use/value
4. be of the opinion that...

Is the "be of" used in eggcracker's example sentence similar to (or the same as ) #1?

eggcrackers : "Many of the planes she flew were of dangerously experimental design."

Thank you in advance.

Eureka!
Thank you all.
I understood the sentence, I suppose.
"Many of the planes she flew were (the planes) of dangerously experimental design."
